Fluid analysis involves system, control volume, and fluid behavior in space. Physical parameters B can be extensive (mass-dependent) or intensive (independent of mass). System properties are determined by summing fluid particle properties
Parameter comes from Latin parametrum, meaning "line through focus". Originally used in mathematics for constants and variables. Now applies to any factor determining variation range
Parabola equation is y = ax² + bx + c, where a is nonzero. Parabola with origin (0,0) is simply y = ax². Parabola opens up with positive a, down with negative a
Hyperbola is formed by intersecting right circular cone with plane at angle. Hyperbola has two axes of symmetry: transverse and conjugate. Center is midpoint of transverse and conjugate axes. Every hyperbola has two asymptotes passing through center
Hyperbola is a conic section with equation similar to ellipse but with subtraction. Looks like two mirrored parabolas with two branches called branches. Centered at point (h, k) with vertices at fixed distance a from center. Foci are located inside each branch, foci are further from center than vertices
Ellipse is a set of points where sum of distances from two fixed points is constant. Major axis connects two foci, minor axis passes through center. Distance between foci is 2c, major axis length is 2a, minor axis length is 2b
